As shown in 2467HFigure 156, Firewall is a Web server with domain name whatever.gicp.cn.
Firewall acquires the IP address through DHCP. Through the PeanutHull server, Firewall informs the DNS
server of the latest mapping between its domain name and IP address.
The IP address of the DNS server is 1.1.1.1. Firewall uses the DNS server to translate www.oray.cn into the
corresponding IP address.
